.SH DESCRIPTION
.LP
.B lastcomm
prints out information about previously executed
commands. If no arguments are specified,
.B lastcomm
will print info
about all of the commands in
.I acct
(the record file). If called with one or more of
.I command-name,
.I user-name,
or
.I terminal-name,
only records containing those items will be displayed. For
example, to find out which users used command `a.out'
and which users were logged into `tty0', type:
.ce
lastcomm a.out tty0
.ce 0
.LP
This will print any entry for which `a.out' or `tty0'
matches in any of the record's fields (command, name, or terminal). If
you want to find only items that match *all* of the arguments on the command
line, you must use the '\-strict-match' option. For example, to list
all of the executions of command
.IR a.out " by user " root " on terminal " tty0,
type:
.ce
lastcomm \-\-strict-match a.out root tty0
.ce 0
.LP
The order of the arguments is not important.
.LP
For each entry the following information is printed:
+ command name of the process
+ flags, as recorded by the system accounting routines:
S -- command executed by super-user
F -- command executed after a fork but without a following exec
C -- command run in PDP-11 compatibility mode (VAX only)
D -- command terminated with the generation of a core file
X -- command was terminated with the signal SIGTERM
+ the name of the user who ran the process
+ time the process exited
.SH OPTIONS
\. .PD 0
.TP
.B \-\-strict-match
Print only entries that match *all* of the arguments on the command
line.
.TP
.BI \-\-user " name"
List records for user with
.I name.
This is useful if you're trying
to match a username that happens to be the same as a command (e.g.,
.I ed
).
.TP
.BI \-\-command " name"
List records for command
.I name.
.TP
.BI \-\-tty " name"
List records for tty
.I name.
.TP
.BI \-f " filename, " \-\-file " filename"
Read from the file
.I filename
instead of
.I acct
.TP
.BI \-\-ahz " hz"
Use this flag to tell the program what
.B AHZ
should be (in hertz). This option is useful if you are trying to view
an
.I acct
file created on another machine which has the same byte order and file
format as your current machine, but has a different value for
.B AHZ.
.TP
.B \-\-debug
Print verbose internal information.
.TP
.B \-V, \-\-version
Print the version number of
.B lastcomm.
.TP
.B \-h, \-\-help
Prints the usage string and default locations of system files to
standard output and exits.
.SH FILES
